Lovi Assistant explains
- Offers moderate hydration for your normal skin due to glycerin and sodium hyaluronate, which plump and moisturize effectively, though these ingredients do not specifically target your primary concern of pigmentation.
- Squalane and camellia sinensis leaf extract provide additional emollient and antioxidant benefits suitable for normal skin.
- The product is generally safe for your skin, with minimal risks of irritation from alcohol and fragrance.
How to apply
- Could be used as part of your AM and PM routine. Start using it 3 times a week and move to daily use if your skin likes it.
- Apply this moisturizer after your cleanser and toner, right before your morning SPF.
- Gently press a small amount of the moisturizer into your skin. Avoid rubbing it too hard so it absorbs nicely.
- For the best moisture, you can apply it when your skin is slightly damp. This helps your skin stay soft and happy.
- Remember to avoid the eye area when applying. Always do a patch test before your first use.

Questions and answers
How well does Tatcha The Dewy Serum work for skin with dark spots?
This serum works moderately well for skin with dark spots, as it provides good hydration but does not specifically target pigmentation. Skin with dark spots needs products with targeted brightening ingredients and effective hydration to truly address uneven tone.
Which ingredients make this serum a good fit for skin with dark spots?
This serum works for your skin because it includes vitamin C in the form of ascorbyl tetraisopalmitate, which helps brighten dark spots while keeping normal skin soft and balanced. However, to truly fade dark spots, this type of product needs targeted brightening ingredients like niacinamide or retinoids.
What does Squalane do for skin with dark spots?
Squalane helps keep skin soft and smooth, but it is unlikely to directly fade dark spots on its own. For hyperpigmentation, this type of product needs added brightening ingredients like vitamin C or antioxidants to help even out skin tone.
What does Hyaluronic Acid do for skin with dark spots?
Hyaluronic acid is unlikely to directly fade dark spots, but it helps keep dry and uneven skin plump and deeply hydrated. To effectively target dark spots, this type of skin needs brightening ingredients like vitamin C or niacinamide alongside your hydrator.
Where does this serum go in a skincare routine for skin with dark spots?
This treatment goes in the evening routine after cleansing and before moisturizing, to keep things simple and safe around sun exposure. Skin with dark spots needs a product of this type that features targeted brightening ingredients to help fade dark spots.
Can I use this serum with retinol, and in what order?
You can use this serum with retinol by applying the serum first to plump and moisturize your skin, and following it with retinol. A moisturizing treatment like this helps prepare your skin and supports its barrier while you use retinoids, though skin with dark spots needs targeted brightening ingredients like vitamin C or niacinamide to specifically fade discoloration.
How often should I use this serum?
You can use this serum in your evening routine, applying it after cleansing and before moisturizing. Skin with dark spots needs a treatment that includes targeted brightening ingredients like vitamin C derivatives or niacinamide to help fade spots effectively.
Can this serum clog pores, cause breakouts or purging for skin with dark spots?
This serum is unlikely to clog pores or cause breakouts for skin with dark spots, as reviews show only a low potential for breakouts. It keeps skin soft and smooth with squalane and glycerin, though darker spots call for dedicated brightening ingredients like vitamin C or niacinamide.
Can I use this serum around the eyes or on my body?
You can use this serum around the eyes, but keep in mind that the skin there is among the thinnest on the body, making it more delicate. While the product is generally safe, a moisturizing treatment used on the body or eye area needs targeted active ingredients like vitamin C or specialized plant extracts to effectively manage dark spots and keep that thin skin looking bright.
Is this serum fragrance-free and alcohol-free?
It contains fragrance (parfum, citral, limonene, and linalool) and drying alcohol (alcohol).
